PAINTERS MASK.

Application tiled February To all 'whom it-mary concern:

BeV it known that we, -GORDON PHILLIPS and PATRICK HANLoN, both citizensof the United States of America, residing at Detroit, in the county ofWayne and State of Michigan, have invented certain new and usefulImprovements in Painters Masks, of which the following is aspecification, reference being had therein to the accompanyingYdrawings;

he invention relates to masks particularl designed for use by paintersand other wor en exposed to injurious fumes, mists and smokes.

The invention consists in the means employed for maintaining a constantsupplyof pure air, and more specifically in the combination between theair supply for the mask and an air brush-for applying the paint. Theinvention further comprises various features of construction ashereinafter set `forth.

ln the drawings: i y

Figure l is a front elevation of the mask;

Figur-e 2 is a side elevation thereof;

Figure 3 is a section showing the air connections;

lFigure l is an elevation showing the connectionbetween the mask and airbrush;

Figure 5 is a cross-section through the eye piece of the mask. Y

. In thepresent state of the art, painting is rapidly performed by theuse oi an air brush, which in its operation ejects the paint in a hnemist against they surface to be covered. @ne objectionable *feature o1?the process is that the paint inist lills the air and renders it unt forbreathing, so that it has.

been found necessary to provide the operators with masks. 'lhese masksare provided with a moist sponge or other means fernltering the air, butit has been found dicult t'o completely purify the air in this manner.Furthermore, the mist oi'r'A paintdeposit on the sponge soon hardens andrenders it impervious. '.lo protect the eyes of the workinanthe ina-skis constructed with a' transparent panel or eye-piece, but the mist olfpaint-deposit on the glass soon obscures the vision. l

'lo overcome the diculties above clebrush-through-which fresh air issupplied` within the mask. We have also provided length or time withoutinjury.

means for preventing the,deposit of paint mist upon the eye-piece, sothat clear vision is maintained.

In detail A is a mask for protecting the face of the workman, preferablyin the form of a hood completely covering the head. This hood ispreferably formed of paper or other light material and may, 'if desired,be provided with a felt pad B at the top for resting upon the operatorshead. 'lhere is' also preferably provided a depending ilexible skirt C.l) are eve openings covered with glass panels, and E is a nose-piece. Fis the air brush which is connected toa flexible air conduit G and adexible paint conduit H; said conduits being respectively connected to asource of compressed air and liquid paint (not shown). l is a. flexibleconduit connecting the air conduit of the air brush with the nose-pieceE, a controlling valve J being provided to regulate the pressure. 'llhespace within Athe nose-piece is'preferably lilled with a sponge or otherporous body K through which' 'the air is distributed and :trom which itpasses into the space within the hood. I are air conduits connectinginto the air conduit l' in advance of the valve d' and leading to theeye-pieces l) and-preferably connecting to annular conduits Msurrounding said eye-pieces with discharge apertures distributedthereabout. The construction is such that currents of air encircling-theglass meet at a point a short distance in iront of the surface ot theglass to prevent deposit of paint mist thereupon.

With the construction as described, theincetta l while the air passing Land annular con- 3 duits M will form a protecting dome over the surfacesof the glass to keep the same clear from paint. Consequentlythe operatoris enabled to continue' 'the work for any What we claim as our inventionis:

1. The combination with a mask having a transparent panel or eye-piece,of means surrounding the space in front oi the eyepiece for. directingcurrents of air across and in frontof the same, and an air conduitconnecting into said mask and current directllg m6511115.

2. The combination with a mask having a transparent panel or eye-piece,of means for supplying air to the mask, and an'annular conduit connectedto the air supplying means outside of said mask` and located near theperiphery of said eye-piece, said conduit having provision for directingair across and in front of said eye-piece.

3. The combination with a mask having a transparent panel or eye-piece,of an annuiar conduit surrounding the space in front of said eye-piece,and an air conduit connecting into said maskand annular conduit, thelatter being provided with a series of discharge apertures on its innerperipheral side for directing currents across and in front of saideye-piece.

In testimony whereof We affix our signatures.
